L296P中文资料HIGH CURRENT SWITCHING REGULATORS数据手册ST规格书

描述 Description

The L296 and L296P are stepdown power switching regulators delivering 4 A at a voltage variable from 5.1 V to 40 V.
Features of the devices include soft start, remote inhibit, thermal protection, a reset output for microprocessors and a PWM comparator input for synchronization in multichip configurations.
The L296P incudes external programmable limiting current.
The L296 and L296P are mounted in a 15-lead Multiwatt® plastic power package and requires very few external components.
Efficient operation at switching frequencies up to 200 KHz allows a reduction in the size and cost of external filter components. A voltage sense input and SCR drive output are provided for optional crowbar overvoltage protection with an external SCR.

简介

L296P属于集成电路（IC）的稳压器-DC-DC开关稳压器。由ST制造生产的L296P稳压器 - DC-DC 开关稳压器DC-DC 开关稳压器 PMIC（电源管理集成电路）产品族中的产品是元器件级设备，用于需要稳定 DC 输入电压和/或将其转换为不同幅度的输出电压的应用。这些器件与称为“控制器”PMIC 的类似产品的区别在于集成了主开关元件，设备提供的电力会通过该元件。
